VThis invention relates'tocertain new and useful improvements inadjustable shelfangle supports for building construction, and moreparticularly to a supporting member of this type which is capable ofboth horizontal and vertical adjustments between the shelfangle andtheanchoragefrom whichfit is supported.l i. j

ln most modern building construction, the floors, interiorbeams andother load-supportingportions are carried by ai'structural frame ofconcrete or steel coveredwithconcrete, and the exterior walls are merelya sheathing of brick, stone, terracotta or other suitable material. Inmost instances, the outer walls are hung on or'supported bytheconcretevframef work. `For the'purpose of vsupport-ing these outer wallsover the window and `door openings, metallicsheli angles were boltedtothe concrete framework, and the lower rowof brick or similar materialsupported on this shelf angle. Y' ln multiple-story buildingconstruction, it is, usual `to support these outer walls at practicallyevery floor level by means of similar shelf angles extendingcontinuous'- ly around the building at each floor, so that any one levelor story of brick work can be removed independently without disturbingthe brick work above orv below that particular level.

In the first practical form of supporting means used, anchorage boltswere-cast into the concrete frame-work, these bolts having threadedouterendiportions which were insorted through holes in the rear verticalflange of the shelf angle. and provided with nuts for holding theV anglerigidly in place. This form of supporting means did not provide anymeans of adjustment', either vertical or horizontal'and since it ispractically impossible to predetermine the exact inal position of theanchorage bolts, it was usually necessary to drill or burn special holesin the shelf angle to receive the bolts, after the bolts were in place.This isla very slow 'and expensive procedure. Metal inserts.have'heretofore been developed which were anchored' in the concretestructure and permitted avertical adjustment ofthe bolts used for.supporting the shelf angle. Even this construction the attachingbolt,and it isdifflcult'to prej determine the proper positioning-'of`the boltv holes inthe angle member. l Y

Tl'ef principal Vobject of the'invention v1s 10 with the Vfront wall 1and flanges 4. Shorter anchoring wings may also'project from theendwalls42.VV It will be understood that these anchoring membersmighttalre a variety of v different forms, their principal functionbeing to provide sufficient anchorage" surface within the concrete framein which the insert iis embedded.l The open rear side of the box- `likestructure is lcovered by a second sheet metal plate 8 which isspot-welded, as at 8', to the side flanges 4. f In the. front face 1 ofthe insert is formed a T-shaped slot or opening, lcomprising a verticalslot 9 of a width suflicient to receive the stem 10 of the bolt, andwith an upper opening 11 largeenough to f permit the insertion of thehead 12 of the bolt (or of the nut 13 if the bolt and nut should beyreversed from the positions shown by yway of example in the drawing).One `or more holesr14v extend througheach side ,flange 4 and rear coverplate8 to receive the :nails used when therinsert is installed,'.ashereinafter described. It will be apparent that thesek improved insertsare very simple and economically constructed of two pieces of sheetsteel by simpleV stamping operations,and when welded together, as at`8,a rigid and permanent assembly is provided. The firstrstep ininstallingthese metalinser-tsr is to mount them temporarily on the innersurface of the outer wall of the wooden fori-n i-n whichithe concrete isto be poured, as` indicated at 15 in Fig. 4. HRather long nails '16 areinserted through the holes'14, .hereinabove referredto, Vand the insert:is inailed against the inner surf-ace ofl the ',wooden form 15, asclearly shown in Fig. v4. It will be noted that the wooden wall oftheformV closes the T-shaped slot in the insert .thatthe concrete cannotenter the box-like Structure. After-the concrete has been poured jand:lhas set, aspindicated at 17 in Figs. 1, 2

:and 3, the wooden forms are tornaway, leaving the metallic insertsfirmly/embedded .with-,inthe concrete structure with the front Ywall 1of the insert substantially Hush with the-outer face of the concretebeam. The projecting ends of the nails 16 can be-cut away., i Y j, In.previous constructions the shelf-angle 18, consisting of thehorizontally extending flange Vllf'and-vfveI-'tieally extending flange2O has been supported byextending the stems YlQnoffthe supporting boltsdirectly through suitableholes formed infthe Vvertical, iange20,'whereby the shelf angle is bolted directly angle and support thesame.

against the concrete beam 17 or against the inserts in case inserts areused. According to the present invention, a suitable hanger isinterposed between the supporting bolt and the shelf-angle, and no holesare necessary in the angle member. In the form here shown, this hangercomprises a rear member 21 and afront member 22,` each formed ofsuitable strap metal, their upper end portions being superposed on'oneanother and 75 provided. with mating openings 23 for receiving thestemv10 of the anchoring bolt. The longerfrear -ha-ngermmember 21 has anoutwardly extending horizontal flange portion '24 at its Vlower'endadapted to project 80 Fbeneath thehorizontal'iiange 19 of the shelfy Theshorter front hanger member 22 is `bent outwardly vand downwardly `at'25and 'provided with a vertically extending endportion 26 adaptedffk tooverlap the upper portion of the vertical fiange 20 of the shelf-angleand prevent same from tilting outwardly. VThe assembly is locked lfirmlyin `position by 'placing the nut 13 and washer 27 on the projecting endpor- 190 tion of the stem 10 of the `bolt and screwing the nut downtightly. j j y In practical use, theinetal yinserts will first beanchored within the concrete structure in the manner describedrin detailhereinabove. "95p At some convenient time after theY concrete hassetandthe forms have been removed, the bolt 10 maybe inserted in placewithin the insert f and the members y21 and 22 of the hanger and the nut13 and washer 27 loosely 100 assembledon the projecting end of thebolt.V At any time thereafter Vthe shelf-angle 18 may be mounted inposition by merely swingingaside the front angle members 22, resting theshelf-angleon the rear hanger mem- T bers l21 and then swinging thefr0-nt members 22 down into position, as shownzin Figs. land y2. V.Itwill be apparent that since there'are no holes or other openings to beengaged' in the shelf-angle, the exact horizontal positioning i'- of theinsertsand hangers is immaterial, since any portion; lengthwise, lof theshelf-angle ymay be engaged by the hanger. VNormally the heads 12 of thebolts will restagainst theflower wall of the box-like structure of l1-i5the insert, but Aincase some one or lmore of these inserts hasnot-'been` accuratelyv aligned .horizontallywith the other inserts, thecorresponding'hangermay be properly positioned'by pushing up thehangerlmembers until 'F120 the supportingl shelfzportion 24 is properly beneaththe horizontalfl-ange 19 of the shelf angle and then screwingthe nut 13tightly j into. position. Suc-ha-.positioningV of the parts isind-icated'inf 2;. 'Inany case,fthe '.125 assemblyzwill be heldl tightlyin place` against either vertical or horizontal movements after the nut13g-has been screwedidown to. draw the head of thefboltfirmly againstthe inner sirde *1 ofthe front wall 1 oftheinsert.

nemers Vertical adjustments might be provided for by forming verticallyelongated openings 23 in the hanger members, in which case anchoragebolts of the type heretofore known might be embedded directly in theconcrete structure and the special form of inserts omitted entirely.

While only a single shelf-angle has been shown as supported from theconcrete frame 17, it will be apparent that two or more superposed rowsof such shelving could be used if desired, the same forms of supportsbeing used for each row of shelving.

It will be seen that this improved supporting device eliminates thenecessity of all holes, slots or machining of any type inf theshelf-angle, which is merely clamped in position and'requires no specialattention or v adjustment before it is mounted or while it is beingmounted on the building framework. The supporting device is formedv of afew simple parts which are easily and economically constructed, and areeasily assembled, and which have ample strength for supporting the loadcarried by the shelf-angles.
